Deredza uye uwedzere kuenzanisa kwekumanikidza

Kugadziridza mota inyaya inofarirwa nevazhinji vatyairi. Kana isu tichigovana pamhando dzose mhando dzemazuva ano dzemuchina, ipapo pachave nezvikamu zviviri: zvehunyanzvi uye zvinoonekwa. Muchiitiko chechipiri, kungoonekwa kwemotokari kunochinja. Muenzaniso weizvi ndeuyu kunamatira kubhomba kana kuchinjisa muchimiro stens auto.

Iko kune zvakare zvakawanda zvingasarudzika zvehunyanzvi kugadzirisa. Kana muchiitiko chekutanga mota inogona kungotaridzika kunge yemitambo, saka kuvandudzwa kwesimba remagetsi hakukanganise pakuonekwa kwemotokari. Asi kana mota isingazivikanwe yaiswa kumhanya, vateereri vanotarisira furore, nekuti ivo vanonzwisisa: muridzi wemota akagadzirira chimwe chinhu chinonakidza.

Zvisinei, kuvandudzwa kweinjini mumotokari hakuwanzo kuve nechinangwa chekuwedzera simba nekuita kwayo. Vamwe varidzi vemota vanozvimisikidza ivo chinangwa chekutora injini. Kune nzira dzinoverengeka dzekuwedzera uye kudzikisira mashandiro echikamu. Ngatimbokurukurai mumwe wavo zvizere. Uku ndiko kuwedzera / kuderera muyero yekumanikidza.

Kuwedzera compression ratio

Zvinozivikanwa kuti compression reshiyo, pakati pezvimwe zvinhu, zvinokanganisa zvakananga injini simba. Kana kumanikidza injini uchishandisa humburumbira kutakura kunotungamira mukuwedzera kwemafuta, saka maitiro aya haatapure hunhu uhwu. Chikonzero cheichi ndechekuti huwandu hweinjini hunoramba hwakafanana (kune rumwe ruzivo nezve zvazviri, verenga pano), asi mafuta ekushandisa ari zvishoma zvishoma.

Vamwe vatyairi vanofunga nezvekuita maitiro aya kuti vawedzere kumanikidza pasina kuchinja huwandu hwemafuta anodyiwa. Kana iko kunwa kwawedzera, izvi zvekutanga zvinoratidza kuti zvimwe zvinokanganisa zviri kuitika muinjini kana sisitimu yekuwanisa mafuta. Kuwedzera kweiyo compression ratio mune iyi kesi hakugone kungochinja chero chinhu, asi, nekupesana, kumutsa kumwe kuparara.

Kana iko kudzvinyirira kwakadonha, iko kusashanda kunogona kuratidza mavharuvhu ekutsva, kutyora kweO-zvindori, nezvimwe. separated article... Neichi chikonzero, usati watanga kumanikidza mota, iwe unofanirwa kubvisa zvisizvo zvakamuka.

Izvi ndizvo zvinowedzerwa kumanikidzwa kwemweya-mafuta musanganiswa zvinopa muinjini inoshanda.

1. Wedzera kugona kweinjini (kugona kweinjini yekutsva yemukati inowedzera, asi iko kunwa hakuchinje);
2. Simba reyuniti yemagetsi rinowedzera nekuda kwemasimba akasimba, ayo anomutsa kupisa kweBTC;
3. Kudzvinyirira kuwedzera.

Mukuwedzera kune zvakanakira, iyi nzira ine yayo mhedzisiro mhedzisiro. Saka, mushure mekumanikidza, iwe unozofanirwa kushandisa peturu neyakawedzera octane nhamba (kune rumwe ruzivo nezve kukosha uku, verenga pano). Kana iwe ukazadza tangi neiyo peturu seyakamboshandiswa, kune njodzi yekugogodza. Apa ndipo kana musanganiswa unotsva usingabatidzi panguva inoiswa raki, asi ichiputika.

Kusadzora uye kusagadzikana kupisa kweBTC kuchakanganisa mamiriro emapiston, mavhavha uye iyo yakazara crank mashini. Nekuda kweizvi, hupenyu hunoshanda hweyuniti yemagetsi hwakadzikira zvakanyanya. Mhedzisiro iyi yakakosha kune chero injini, zvisinei nekuti iri maviri-sitiroko kana ina-sitiroko yuniti.

"Chironda" chakadai hachinetseke chete neinjini yepeturu iyo yakamanikidzwa kushandisa nzira iri kutariswa, asi zvakare kubva kuchikamu chedhiziri. Saka kuti kuwedzera kweiyo compression reshiyo hakukanganisa mashandiro einjini, nekuwedzera kuchinjika kwayo, zvichazo fanirwa kudururira mafuta mutangi yemota yepeturu, toti, kwete 92, asi yatove iyo 95th kana kunyange iyo 98th brand.

Usati waenderera mberi nekuvandudza kwechikwata, munhu anofanirwa kuyera kana zvichizonyatso ruramisa hupfumi. Kana dziri mota dzakaiswa gasi kumisikidzwa (verenga nezve maficha ekuisirwa kweLPG zvakasiyana), ipapo kudonhedza kunenge kusamboitika mavari. Icho chikonzero cheichi ndechekuti gasi rine rakakwira RON. Ichi chiratidzo chemafuta akadaro chi108, zvekuti muinjini dzinomhanya pane gasi, zvinokwanisika kuwedzera kudzvanya chikumbaridzo pasina kutya.

Nzira mbiri dzekuwedzera huwandu hwekumanikidza

Chinhu chakakosha cheiyi nzira yekumanikidza injini kushandura vhoriyamu yekamuri yemoto. Iyi ndiyo nzvimbo iri pamusoro pepistoni, umo mafuta uye chikamu chemhepo yakadzvanywa yakasanganiswa (yakananga jekiseni masisitimu) kana musanganiswa wakagadzirwa wakagadzirwa.

Kunyangwe kufekitori, iyo inogadzira inoverenga imwe compression ratio yeiyo chaiyo unit. Kuti uchinje iyi paramende, iwe unofanirwa kuverenga kune kukosha kupi iwe kwaunogona kudzikisa huwandu hweiyo yepamusoro-pisitoni nzvimbo.

Ngatitarisei mbiri dzenzira dzinozivikanwa kwazvo idzo kamuri iri pamusoro pepistoni kumusoro kwepakafa inova diki.

Kuisa yakatetepa injini gasket

Chekutanga kushandisa yakatetepa humburumbira musoro gasket. Usati watenga chinhu ichi, unofanirwa kuverenga kuti yakadii iyo nzvimbo pamusoro pepistoni inoderera, uye zvakare funga nezve maficha emapiston.

Dzimwe mhando dzemapistoni dzinogona kusangana nemavharuvhu akavhurika kana kamuri remoto radzikira. Maumbirwo ezasi anoenderana nekuti nzira yakafanana yekumanikidza injini ingashandiswa here kana kuti kwete.

Kana, zvisinei, kunoitwa danho rekudzikisa huwandu hwenzvimbo pamusoro pepistoni uchishandisa gasket rakatetepa, saka zvakakodzera kuti utarise zvakanyanya mapistoni ane pasi pe concave. Pamusoro pekuisa zvikamu zvitsva nezvisingaenzaniswi, iwe uchafanirwa kugadzirisa nguva yevhavha (chii ichi, zvinodaro pano).

Kana iyo gasket yatsiviwa nekuda kwekuneta, musoro unofanirwa kuve jecha. Zvichienderana nekuti kangani maitiro akamboitwa, vhoriyamu yepamusoro-pisitoni nzvimbo inodzikira zvishoma nezvishoma.

Usati watanga kuwedzera compression ratio, zvakakosha kuti uone kuti kukuya kwakaitwa nemuridzi wemota yapfuura kana kwete. Iko mukana weiyi nzira inoenderanawo neizvi.

Cylinder inofinha

Nzira yechipiri yekushandura compression ratio ndeye cylinder bore. Mune ino kesi, isu hatibate musoro iwo wega. Nekudaro, huwandu hweinjini hunowedzera zvishoma (pamwe neizvi, mafuta ekushandisa anowedzera), asi huwandu hweiyo yepamusoro-pisitoni nzvimbo haichinje. Nekuda kweizvi, iro rakakura vhoriyamu reVTS richamanikidzwa kusvika pahukuru hweiyo isina kuchinja mwenje kamuri.

Pane akati wandei nuances ekufunga kana uchiita iyi maitiro:

1. Kana injini ikamanikidzwa kuwedzera simba, asi kwete pamubhadharo wekuwedzera kwemafuta, nzira iyi haina kukodzera. Ehe, iyo "makaro" emota anowedzera zvishoma, asi ichiripo.
2. Usati wabereka humburumbira, iwe unofanirwa kuyera kuti ndeapi mapistoni auchazoda. Chinhu chikuru ndechekuti iwe unogona kusarudza chaiyo zvikamu mushure mechimanje manje.
3. Kushandisa nzira iyi kunozotungamira kune mamwe marara - iwe unofanirwa kutenga asiri-akajairwa mapistoni, mhete, kubhadhara mari kune nyanzvi yekutendeuka uyo achaita basa nemazvo. Uye izvi zviri kuwedzera kune chokwadi chekuti iwe uchafanirwa kuchinjira kune imwe mhando peturu.
4. Mhedzisiro yakakura yekuwedzera compression ratio ichaonekwa mune iyo mota iyo ine diki CC yakatarwa kubva kufekitori. Kana muchina wacho wakashongedzerwa neyakatowedzerwa yuniti (kubva kufekitori), ipapo hakuzove nekuwedzera kwakakosha kubva munzira yakadaro.

Kuderedza compression reshiyo

Maitiro aya anoitwa kana kusekana kweyuniti kuchidikanwa. Semuenzaniso, vatyairi vaida kuchengetedza pamafuta vakaderedza SS. Iyo yepazasi compression ratio yemhepo-mafuta musanganiswa inobvumira kushandiswa kwepeturu ine yakaderera octane nhamba.

Munguva yakapfuura, musiyano uripo pakati pe92nd ne76 waive wakakosha, izvo zvakaita kuti maitiro acho abudirire. Nhasi, peturu yechi76 chiitiko chisingawanzoitika, chinomanikidza basa remutyairi kana achifanira kufamba chinhambwe (mashoma magasi anotengesa mafuta aya).

Kwazvino kwakadaro kwakakanganisa chete mune yekare mota mamodheru. Mota dzemazuva ano dzakashongedzerwa nezviri nani mafuta masisitimu ari kuda peturu. Nechikonzero ichi, kuchengetedzwa kuri pachena kunogona kutokuvadza mota, pane kubatsirwa.

Kuderedzwa kwekumanikidza kunoitwa maererano nechirongwa chinotevera. Musoro wesilinda unobviswa woiswa jecha. Panzvimbo peyakajairwa gasket, akaisirwa maviri akajairwa analogue, pakati payo inoiswa aruminiyamu ine yakakodzera ukobvu inoiswa.

Kubvira pakushandisa nzira iyi, kudzvinyirira kwadzikira, mota yemazuva ano icharasikirwa nemasimba. Kuti uchengetedze ruzivo rwekutyaira, mutyairi anofanirwa kutenderera injini zvakanyanya, izvo zvinokanganisa mashandisiro ayo kumusoro. Peturu, inova yehunhu hwakaipisisa, inoburitsa mweya wakachena zvishoma, ndosaka chinokonzeresa chichizopera zviwanikwa zvacho nekukasira uye chinoda kuchinjwa kazhinji.

Zvakakodzera here kuchinja kubva pa95 kuenda pa92 pamutengo wakadai, hongu, iri ibhizinesi remunhu wese Asi kushandisa njere kunoraira: chinodhura injini chinjisheni kuitira kuti ifungidzirwe pamafuta asingadhuri kushandiswa zvisina musoro kwemari. Izvi ndizvo, nekuti imwe marara ichaonekwa nenzira yekugadzirisa mafuta (kuchenesa majekiseni) kana zvinokonzeresa.

Chikonzero chega mota yazvino ingangoda kukwidziridzwa kwakadai kuisa turbocharger. Kana michina yakadaro ikabatanidzwa, kuputika kunogona kuitika mumotokari, saka, vamwe vanowedzera vhoriyamu yenzvimbo inopfuura-pisitoni.

Kuwedzera, isu tinokurudzira kutarisa vhidhiyo ongororo yekuwedzera / kudzikisa iyo compression ratio:

Mibvunzo nemhinduro:

Ko compression ratio inogona kuwedzerwa here? Ehe. Iyi nzira inokubvumira kuti uwedzere iyo chaiyo simba remota, uye zvakare inowedzera kushanda kwemota sejini yekupisa (kubudirira kunowedzera pamwero wekuyerera wakafanana).

Iyo yakakwirira iyo compression reshiyo, zviri nani? Nekuwedzera kwehuwandu hwekumanikidza, simba rejini rinowedzerawo, asi panguva imwe chete mumajini epeturu njodzi yekuputika inowedzera (iwe unoda kuzadza peturu neRON yakakwirira).

Ko compression ratio inowedzera sei? Kuti uite izvi, unogona kuisa yakaonda cylinder musoro gasket kana kukuya kumucheto kwezasi kwemusoro. Nzira yechipiri ndeyekuboora masilinda ehukuru hukuru hwepiston.
